Three methods commonly used for surface treatment of standard parts

1. Electroplating of standard parts

Electroplating of standard parts means immersing the parts of the fastener that need to be electroplated into a specific aqueous solution. The aqueous solution will contain some deposited metal compounds, so that after passing through the aqueous solution by electric current, the metal substances in the solution are deposited and adhered tightly. The immersed part of the firmware. Electroplating of standard parts generally includes galvanizing, copper, nickel, chromium, copper-nickel alloy, and the like.

2, standard parts of hot dip galvanizing

Hot dip galvanizing of fasteners is to immerse the blown abrasive fasteners of carbon steel into the bath of molten zinc with a heat of about 510 ° C, so that the iron-zinc alloy on the surface of the fastener will turn into blunt Zinc is used to obtain a surface treatment effect. The price of hot dip galvanizing of standard parts is higher than that of electroplating, which is about 1.5 to 2 yuan per kilogram.

3. Mechanical plating of standard parts

The mechanical plating of standard parts means that the surface of the standard part is impacted by the specific physical and chemical means with the powder of the plated metal, so that the plated metal forms a coating on the surface of the fastener by cold welding to achieve the surface treatment effect. . Mechanical plating of standard parts is mainly suitable for screws and nuts

Zinc Alloy Die Casting with Tumbling have a good surface roughness, strength and elongation, Which are widely used in a variety of ornaments, such as furniture, accessories, door handle ,architectural decoration, bathroom accessories, lighting parts, toys, tie clips, belt buckles, various metal buckle and so on,they are required a good surface treatment performance.

Zinc Alloy Die Casting with Tumbling have their own purposes, need to meet the performance requirements.
(1) mechanical properties, tensile strength, when the material fracture resistance;Elongation, brittleness and plasticity of the measure;Hardness is the resistance of the material surface is pressed into a hard object or friction caused by plastic deformation.
(2) state of the working environment: temperature, humidity, media contact with the workpiece and air tightness requirements.
(3) precision: accuracy and dimensional stability can be achieved.
